摘要： A sensing instrument includes: a reference sensor including a reference piezoelectric resonator not adsorbing a substance to be sensed; a reference oscillator circuit oscillating the reference piezoelectric resonator; a measuring unit receiving an oscillation output of a sensing oscillator circuit and an oscillation output of the reference oscillator circuit in a time-series manner to measure frequencies of the oscillation outputs of the oscillator circuits; and a data creator creating time-series data of a difference between a frequency in a sensing sensor and a frequency in the reference sensor, based on the frequencies of the oscillation outputs of the oscillator circuits obtained by the measuring unit. Therefore, a frequency changed due to a factor other than the adsorption of the substance to be sensed is cancelled.

摘要： To provide a sensing device having a high processing power and capable of high-accuracy measurement. It is determined whether or not an oscillation frequency is stabilized while a buffer solution is supplied to a quartz-crystal resonator 4. from a syringe pump 10. When it is determined that the frequency is stabilized, a second valve 14. is switched to a sample solution supply mode to supply a sample solution in an injection loop 14a. to the quartz-crystal resonator 4. An instant at which the sample solution reaches the quartz-crystal resonator 4. and an instant at which the sample solution finishes passing through the quartz-crystal resonator 4. are automatically found based on a supply flow rate of the buffer solution, a volume of the injection loop 14a, a volume of a supply channel supplying the sample solution to the quartz-crystal resonator 4, and an instant at which the second valve 14. is switched to the sample solution supply mode. An oscillation frequency before the sample solution reaches the quartz-crystal resonator 4. and an oscillation frequency after the sample solution passes through the quartz-crystal resonator 4. are found, and a difference between the oscillation frequencies is obtained.

摘要： Time-series data of piezoelectric resonator frequencies for each concentration of a substance to be absorbed is collectively displayed. An absorption start point of a substance to be absorbed is set in pieces of the time-series data. An editor combines and displays at least frequency variation regions in the data. The absorption start point setting is realized when an operator positions a pointer and clicks on the time-series data, or when an absorption start signal is output at the time when a solution is supplied.
